Occassionally when I'm at big department store, I'll play with those keyboards that have drum noises and such associated with some of the keys. I can never play those keys like I can a real set of drums, as it's just too small and difficult and my hands don't work that well. Then I saw this video link in the latest b3ta newsletter, and was blown away. The video is of a guy playing percussion on the Prodikeys keyboard -- a combo dual computer with computer and MIDI piano keys -- and it's damn impressive.
